POLYTONE K-93 is a Ketone Formaldehyde Resin used in the manufacture of flexographic inks, gravure inks, lamination inks, lacquers and paper coatings.. These resins are highly effective in imparting gloss, adhesiveness, leveling and also in increasing the solid content leading to a reduction in the VOC. The hydroxyl polarity leads to better adhesion and wetting of pigments and surfaces. POLYTONE K-93 is used in the manufacture of all types of nitrolacquers and are useful in the manufacture of PVC lacquers and for polishing lacquers and finishes for the surface treatment of wooden furniture and articles. POLYTONE K-93 is also useful in heat seal coatings, primer and base coatings, gasoline resistant coatings, nail lacquers etc.
POLYTONE K-93 is soluble in alcohols (not in methanol), ketones, esters, glycol ether acetates, as well as in some aromatic & chlorinated hydrocarbons. They are however not soluble in water and in aliphatic hydrocarbons.
POLYTONE K-93 is compatible with different types of nitrocellulose, benzyl cellulose, ethyl cellulose, cellulose acetate, polyvinyl chloride, chlorinated rubber, as well as in many synthetic
resins e.g. alkyd resins, pthallic resins, UF resins, polyvinyl butyryl resins, polyamide, phenol formaldehyde condensation resins etc and a multitude of plasticizers.
Available in 25 Kg bags.
